Metal Machining Guide: Turning, Milling and Grade Selection

Metal Machining Guide: Turning, Milling and Grade Selection

Short answer: Machining turns stock into parts by turning, milling, drilling and grinding; the alloy and temper decide cutting speed, tool life and surface finish, so free-machining carbon steels, 6061 aluminum, brass and copper run fast while stainless work-hardens and nickel alloys cut slowly.

Processes and Cutting

Turning, milling, drilling and grinding remove metal to shape; the strength and hardness that affect cuttability are in our Vergleich der Stärken, the treatment that sets hardness in our Heat Treatment Guide and the tooling in our Tool Steel Types Guide, with grade families in our Types and Grades of Steel.

Material and Machinability

Free-machining carbon steel, 6061 aluminum, brass and copper cut fast, while stainless work-hardens and nickel cuts slowly; the stock is in our Carbon Steel Supplier, Stainless Steel Supplier, Aluminum Supplier und Copper Supplier.

Tooling, Speed and Finish

Sharp tooling and the right speed keep heat and burrs down; the tooling grades are in our Tool Steel Types Guide, the finish options in our Surface Treatment Guide, fatigue limits in our Fatigue Guide and the data in our Vergleich der Stärken.

Stock, Cost and Tolerance

Buying the right temper and size cuts machining cost; the dimensional limits are in our Tolerances Guide, the proof in our Mill Test Certificate Guide, packing in our Export Packing Guide and the grade base in our Arten von Kohlenstoffstahl.

Häufig gestellte Fragen

Which metal machines fastest?

Free-machining carbon steel, brass, copper and 6061 aluminum.

Why is 304 stainless harder to cut?

It work-hardens, so sharp tools and steady feeds are needed.

Does temper affect machining?

Yes — softer tempers machine easier but may need hardening after.

How accurate is CNC machining?

Tight tolerances are held per our metal tolerances guide.

Can HXSCO supply machined stock?

We supply the right grade and temper; ask about sawn or rough-machined blanks.
